The invention relates to an electrostatic attracted weight sorting method and equipment, which can electrify the to-be-sorted objects with a charge, the sorting mechanism with another charge. The attracting force between the to-be-sorted objects and the sorting mechanism can reach an expected value through regulating the distance between the to-be-sorted objects and the sorting mechanism. Therefore the to-be-sorted objects with a weight smaller than the sorting standard are attracted by the sorting mechanism; the to-be-sorted objects with a weight larger than the sorting standard can not be attracted by the sorting mechanism, while the to-be-sorted objects with a weight equal to the sorting standard maintain the original state. The to-be-sorted objects being attracted and the to-be-sorted objects not being attracted are collected respectively, thus the sorting process is completed. Compared with the existing weight sorting method, the method has the advantages of high efficiency and sorting precision, convenient in popularization, and is particularly suitable for the weight sorting of solid preparations such as capsules, tablets and pills during the production process of medicine so as to remove non-conforming products and enhance the overall quality of medicines.
